1. A collaborative Web site comprised of the perpetual collective work of many authors. Similar to a blog in structure and logic, a wiki allows anyone to edit, delete or modify content that has been placed on the Web site using a browser interface, including the work of previous authors. In contrast, a blog, typically authored by an individual, does not allow visitors to change the original posted material, only add comments to the original content. The term wiki refers to either the Web site or the software used to create the site. The first wiki was created by Ward Cunnigham in 1995

An essentially omnicontextual word that can be utilized in an endless number of ways, from being an exclamatory particle to an always convenient filler word. 'Wiki' can never really be overused, owing precisely to its almost infinite range of nuance, expression, wordplay and compound possibilities. It could be said to be the most versatile word in the English language.

"I totally wikied it up."
"That's pretty wiki"
"There's a wiki in my pants...how the wiki did that get there"
"Wiki!"
